. BACKGROUND OF THEINVENTION A still further object of this invention isto provide an attachment for windows which can readily be adapted todifferent size windows.

the elements at all times, they must be pe'riodicallycleaned andmaintained. v

In recent years, screen panels substantially half the size of the windowhave been providedwith commercially available storm windows. Thus, aclear view was possiblethrough a portion of the window. However, the useof double pane. windows has eliminated the need for storm windows.-

The roller-type screen, which remains concealed except when the windowis open,overcomes many of the objections to the screens described above.The roller-type screens developed heretofore, however, havefnot receivedwide acceptance. The main reason for this is the relatively complicatedand expensive mounting arrangements used on these screens. in the knownprior art devices, extensive modification,

of the window sash or window frame is necessary to install the screen.

It is normal for the builder of today to purchase window frames andsashes fromcompanies specializing in this type of product. The builderthen installs the window units in the wall structure of the building,and'the window stool and trim strips are added to completetheinstallation. Because of labor and material costs, the builderscannot perform costly niodifrcations in the purchased window units..Thus,'roller-type screens which mount on the frame or in the modernbuilding methods.

SUMMARY OF INVENTION This invention is' directed to .a window and screenassembly in which a roller-type screen is mounted in the window stool.

The window stool is formed with a cavity in the interior sash are notpractical with thereof, and a mounting cylinder is'rotatably mounted inthe cavity. The-screenis coiled onthe mounting cylinder, and

Other objects reside in the novel combination and arrangement of partsand in the details of construction hereinafter illustrated and/ordescribed.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to the drawings bynumerals of reference and particularly to FIG. I, numeral 10 designatesthe lower portion of a double hung window. Window 10 comprises a windowframe 12, a lower sash l4, and a window stool I6.

- Window frame 12 comprises vertical frame members 20 I connectedtogether at their upper ends by means of a header,

not shown, and at their lower ends by means of the usual window sill 22.Frame 12 is adapted to be set into an opening in a building and attachedto the studding thereof in the usual manner.

Lower sash 14 is slidably mounted'in frame 12 and is carried therein bya pair of channel members 24. As shown in FIG. I,

grooves are provided in the channel members 24 for both the lower sashand upper sash, not shown. Sash 14 comprises a pair of vertical stiles30, an upper rail, not shown, and a lower springs in the interior of thecylinder serve to maintain the screen in roll form. The screenextendsfrom the cavity through a passage in the rear of the stool and isdetachably connected to the lower rail of the sash.

When the window sash is raised, the screen unrolls and closes the openspace between the sill and. the lower rail of the sash. When the sash islowered to close the window, the screen is automatically rolled back onthe mounting cylinder, and the screen is hidden from view.

The roller screen unit is completely contained in the window stool. Acomplete window unit, with exception of the stool, can be installed in abuilding using standard purchased parts. The stool containing the rollerscreen unit is mounted on the sill to complete the window installation.

A main object of this invention is to provide a screen for a window ofthe type described which can be installed on the window withoutmodification of the window frame or window sash.

Another object of this invention is to provide a screen for'a slidablymounted window in which the screen is completely concealed except whenthe window is open.

A further object of this invention is to provide a screen attachmentwhich is particularly suitable for double pane windows. Y

A further object of this invention is to provide a roller-type screenfor a window in which the screen can be easily and quickly installed orremoved. Y

rail 32. The various stilesand rails are recessed to receive a windowpane 34, preferrably of the double-pane type. Handles 36 are mounted onlower rail 32 to provide a means for manually raising and-lowering thesash. A guide strip 37 and a trim strip 38 are mounted to frame members20 at each side of the window to conceal the front edges of channelmembers 24 and enhance the appearance of the window.

Window stool 16, as shown in FIGS. 1-4 and 7 is formed with a flat topsurface 40, a rounded front surface 41, and a cavity, or opening, 42 inthe interior thereof. With reference to FIG. 3, the end portions 44 ofthe stool are solid, and flat 'surfaces 48 are provided to abut againstthe sill 22 when the stool is mounted in the window. End plates 50 aremounted on the ends of stool l6 and horizontal portions 52 on the plates50 are adapted to rest on the upper surface of sill 22 to support thestool thereon. Stool 16 is held in place in frame 12 by means of screws54 which extend through tabs 56 on plates 50 and into frame members 20.

A roller screen assembly 60 is mounted in the cavity 42 in stool 16.Screen assembly 60 comprises screen 61 which is adapted to be rolled ona mounting cylinder 64. It has been found extremely advantageous to makethe screen 61 from fiberglass because of the flexibility of thismaterial; however, other well known screen materials may be used.

Mounting cylinder 64 is rotatably mounted in cavity 42. One end of themounting arrangement is shown in FIG. 4. it being understood that themounting elements are the same for both ends. As cylinder 64 rotates tofeed out screen 6i, it winds coil springs 66 fixed to a disc 67 oncylinder 64 and to elements 69 which are fixed against rotation.Elements 69 exbrackets 72. Brackets 72 are fixed to the end walls ofcavity 42 by screws or other means. A cover plate 73 (FIG. 2) isrcmovably mounted to the stool to cover cavity 42.

Screen 61 is detachably connected to the lower rail 32 of the sash 14 bymeans of hooks 75 (See FIG. 6) which are .pivotally mounted in a strip76 fixed to the free end of screen 61. Hooks 75 are adapted to extendaround pins 78 extending from-handles 36. A groove 80 is formed in strip76 for receiving the hooks 75 when the screen is detached from thewindowv It will be apparent from the foregoing description thatapplicants have disclosed a simple and efficient means for mounting aroller screen in a window. No modification of the window frame or sashis necessary to utilize applicants invention. The screen is readilyaccessible for replacement or repair, if necessary. Further, the screenis completely concealed when the window is closed, thereby facilitatinga clear view through the window. No slots are formed in the frame, andthus, the disclosed invention is free from leakage problems which resultwhen the roller screen is mounted under the sill.

In the operation of applicants invention, the screen 61 closes the openspace when sash 14 is raised. Springs 66 exert a constant tension on thescreen so that the screen is rolled on cylinder 64 as sash 14 islowered. ln event the screen is not desired, hooks 75 can be lifted offpins 78, and the screen will be rolled on cylinder 64 by springs 66. Ifdesired, vertical elements, not shown, can be attached to strip 76adjacent the side edges of screen 61 to prevent the screen end frombeing pulled back into the stool when it is detached from the window.

While this invention has been described in connection with a particularembodiment thereof, it will be understood that it is capable ofmodification, and this application is intended to cover any variations,uses, or adaptations following, in general, the principles of theinvention and including such departures from the present disclosure ascome within known or customary practice in the art to which theinvention pertains, and as fall within the scope of the limits of theappended claims.
